Reduced axle sag with Timbren suspension enhancement

Just like the rear of your vehicle will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall vehicle handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory suspension.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you're carrying off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will help raise the front end of your vehicle when you're using heavy equipment like a snowplow. This ensures that your headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off-center or has an extension, the springs will automatically compensate for this as well.

An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

The Timbren Front Suspension has performed as advertised, was very easy to install and has improved my truck’s overall ride quality. I would totally purchase again and will eventually get them for the rear. Only complaint was I received two right side brackets in the kit and had to call e-trailer for a left side bracket. They referred me to Timbren. In my opinion, a better customer service approach would have been to call them for me. Since it’s there vendor. Timbren did send me the correct part - begrudgingly though. 514546

Review from a similar Aeon Spring System in Vehicle Suspension


These are one of the best products ever! Simple, effective and a reasonable price. They are carefree, invisible when unloaded and very easy to install yourself. I tow a 37ft 12,500lb 5th wheel with my 2018 2500HD. Though my truck already handled the load well, these make the ride more stable and controlled. Lifts the rear up about 1.5 inches as well as keeps things centered from left to right. What's most important when towing is keeping the steer axle on the road. Though I recommend them for any towing configuration; for those of you that push the limits, these are a must have. Brilliant product! Thanks Timbren for the magic bullet! 708124

Review from a similar Aeon Spring System in Vehicle Suspension


Installed this on my 2009 Caravan because when I had a hitch mount 4-bike platform rack hanging off the back and was loaded with camping gear and family, the rear suspension was terrible, it would bottom out, and my headlights pointed up so that everyone would flash their brights at me. New shocks helped, but did not solve the problem. This product did fix the problem and I am very happy. I was concerned about the feel when the van us unloaded, but this has not been an issue. I highly recommend this product. 796869

Doesn't get any easier for an install. A jack, some soapy water and a couple pieces of 2x4. In about 5 minutes you're done. Took out almost all sag when I dropped my travel trailer on the ball. Great addition to the suspension. 488109

Review from a similar Aeon Spring System in Vehicle Suspension


I bought these as a replacement for "air bags" which I had two different sets, which failed over 10 years. i would say this product is helpful with pulling a trailer and lighter loads but from time to time I haul heavier loads and this product doesn't offer as much help/support as the air bags. This product is a little cheaper and if they don't weaken over time they will be a help. I have added additional leaf springs to two different pickups but then you end up with a stiffer ride full time. 421383

I ordered timbrens for the front and rear of my chevy 2500. I have a 2000 lb truck camper and I wanted something to help carry the load a little better. I had no idea that my front bump stops had worn away to almost nothing until I installed these. They have worn well and performed well so far. 628835

Review from a similar Aeon Spring System in Vehicle Suspension


Rear suspension pads work great. Ride is still like factory with no load unless driving over a big bump at high speed. When towing a 32 foot travel trailer the sag in back end of truck is greatly reduced with a lot more control. Easy to install. The downside is when truck is full with passengers and not towing anything the added weight makes the ride rougher. Shipped on time. 575558

I have a Timbren rear suspension system on my 1982 Chevy truck that I still own, and after 20 years they still work fine. This latest set installed easily on my 2001 F-250 and they work just as well with and without a load. 440182

  • Air Bag Helper Springs for a 1995 Chevy Suburban 1500 4x4
    We have air bag help springs for the rear axle of your 1995 Chevy Suburban K1500 but there are no options for the front. But there are other options we can use for the front. Starting with the front you can use Timbren springs # TGMFK35C. These will be easier to install than air bags and require no maintenance. The front of the vehicle usually stays pretty constant in terms of ride height and the amount of weight at the front so the fixed Timbren springs are ideal. For the rear axle...

  • Will Timbren Front Suspension Helper Springs Raise the Height at the Front of a 1998 Chevy Tahoe
    Generally speaking, Timbren front axle suspension enhancement such as # TGMFK35C for your 1998 Tahoe will be engaged all the time. While this doesn't mean that the front will be lifted (if it is it would be a fraction of an inch based on where this kit installs) the front end will not sag as much, if at all, which can give the illusion that the front is a little higher.

  • Will Timbren Suspension Enhancement for 1997 Chevy Suburban Affect Ride Quality
    When installing the Timbren Front Suspension Enhancement System # TGMFK35C on your 1997 Chevy Suburban, your unloaded ride quality may be a bit more stiff due to the rigidity of the rubber springs on the axle, but not in any extreme manner, and mostly on roads that are not particularly smooth. The trade-off, of course, is that the Timbrens are absolutely going to be a boon to the front end of your '97 Suburban, saving it from the wear and tear you mentioned because they will absorb...

  • Recommended Front Hitch, Snow Plow and Front-Axle Suspension Jounce Spring Kit for 1994 K2500 4x4
    For your 1994 Chevy K2500 4x4 the front-mount hitch I recommend is the no-drill Curt model # 31042 which fits so long as you do NOT have a 34-inch frame width. This hitch offers a 500-lb vertical load rating, plenty for a snow plow like the 82-inch K2 # K2AVAL8219 or one of the others shown on the linked page. With a heavy front-end plow load on the truck's suspension you might want to consider a suspension helper spring kit to help offset that load and reduce front sag. If your K2500...

  • Suspension Enhancement Recommendation for a 1994 Chevy 3500 Truck
    Was your truck built on a cab and chassis style frame? If so, you would need the # TGMFK35C for suspension enhancement. An easy way to determine is to measure the outside to outside dimension of your truck frame. If that distance is 34 you have a cab and chassis truck.
